Underwater image quality assessment

Journal of the Optical Society of America A, 2023
To obtain high-visual-quality underwater images by image post-processing, many underwater image restoration and enhancement methods have been proposed. Underwater image quality assessment (UIQA) methods have been developed to compare these restoration and enhancement methods.

Deskewing of Underwater Images

IEEE Transactions on Image Processing, 2015
We address the problem of restoring a static planar scene degraded by skewing effect when imaged through adynamic water surface. In particular, we investigate geometric distortions due to unidirectional cyclic waves and circular ripples,phenomena that are most prevalent in fluid flow.

A simple underwater imaging model

Optics Letters, 2009
It is commonly known that underwater imaging is hindered by both absorption and scattering by particles of various origins. However, evidence also indicates that the turbulence in natural underwater environments can cause severe image-quality degradation.
